Function "output damping" (058)

Influences the time an output requires to react to a sudden level jump (63% of steady
state). A high value attenuates, for example, the influences of rapid changes on the
measured variable.
User input:
0...255 s
The default value depends on the selected application parameter
"process cond." (004).

7.10 Funktion "upper block.dist" (059)

A window under the process connection can be suppressed when there are strong
reflections near the process connection or nearby internals, long nozzles or struts.
• The blocking distance is measured from the bottom edge of the process connection.
The standard top blocking distance is 200 mm (coax 0 mm).
• All echos are suppressed within this blocking distance.
• As the level echo could possibly be suppressed (and there is no guarantee that no
other significant echo is available), a 10 cm long safety distance is placed in front of
the blocking distance (see "safety distance" (015) function on page 28).
• The customer can set the Levelflex to respond to circumstances when the product is
within this zone (safety distance) (see page 28).

b. The indicated blocking distances are prearised. At media with DC >7, the
upper blocking distance UB can be reduced for rod- and rope probes on
0.1m. The upper blocking distance UB can be entered manually.
c. At DC >7, the lower blocking distance LB increases to 0.07 m for rod pro-
bes.
